What does this company actually do?

I have read all of their announcements and gone right through their website. I still can’t work it out.

They say they are a platform or marketplace or exchange or something like that. What are they actually doing? I assume that they are not actually providing cyber security software to businesses, but finding those cyber security software businesses for small and medium size businesses. I’m probably wrong and I would appreciate any guidance. However if that is indeed what they are doing, I don’t understand why businesses couldn’t find cyber security software themselves?

And what I also cannot understand, is if they are geared towards small and medium size businesses like their website suggests, why is seemingly most of their revenue from the US government?
